Hello, I ran into a problem with the JFFS2 filesystem driver implemented in U-Boot. I've got a NAND device that has correctable ECC errors (corrected somewhere in mtd/nand/nand_base.c). The NAND driver tells the filesystem layer (jffs2_1pass.c) above that there occurred correctable ECC errors and returns with a "value > 0". The JFFS2 driver recognizes the corrected ECC errors as real error and skips this block because the only accepts a "return value == 0" as correct. This problem exists for over 8 years (I checked version 2010.09) so I'm a little bit worried that I interpreted something wrong or didn't get the whole context. Can someone confirm this bug (and the bugfix) in the u-boot jffs2 driver? There was a mail in 2012 that mentioned the same problem, but there was no patch: http://u-boot.10912.n7.nabble.com/JFFS2-seems-to-drop-nand-data-with-ECC-corrections-td142008.html Sometime after this discussion the return value of nand_read() changed from -EUCLEAN as correctable ECC error to a positive value with the count of ECC corrected errors. With kind reguards, Uwe Engling |
